基站定位是利用三家运营商的信号发射塔（基站）进行定位。GPS是卫星定位，最少接收三个卫星信号。GPSone是模拟GPS的定位方式，通过接收三个基站的信号来实现定位。-Base station positioning is the use of three operators of signal transmission tower (base station) for positioning. GPS is a satellite positioning, at least three sate

基于终端至基站信号传播时间的TOA三维定位算法 -Based on the terminal to the base station signal propagation time of TOA three-dimensional localization algorithm
